UNITED STATES PATENT OFFICE.

AARON D. LEWIS, OF CANTON, MISSOURI.

ELECTRIC PERFORATlNG-PEN.

SPECIFICATION forming part of Letters Patent No. 485,767, dated November8, 1892.

Application filed June 30. 1892. Serial No. 438,605. (No model.)

To wZZ whom it may concern:

Be it known that I, AARON D. LEWIS, a citizen of the United States,residing at Canton, in the county of Lewis and State of Missouri, haveinvented a new and useful Electric Perforating-Pen, of which thefollowing is a specification.

This invention relates to electric perforating-pens; and it has for itsobject to provide an improvement in devices of this character adapted tobe used in connection with an ordinary pen to provide means forperforating and indenting the writing material in order that noalterations or erasures can be made in the writing without detection;and to this end the invention contemplates supplemental improvementsupon a contemporaneous joint application filed by me and SilasWither-ell April 23,1892, Serial No. 430,384.

With these and many other objects in view, which will readily appear asthe nature of the invention is better understood, the same consists inthe novel construction, combination,'and arrangement of partshereinafter more fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a perspective view of anelectric perforatingpen in the hand of the operator. Fig. 2 is avertical longitudinal sectional View of the same. Fig. 3 is a sectionalview on the line 3 3 of Fig. 2. Fig. 4 is a detail in perspective of thehand-rest. Fig. 5 is a detail perspective view of the writing-pen.

Referring to the accompanying drawings, A represents atubular hollowpenholder havingat one end the ordinary pen-receiving socket, whichreceives the writingpen B, adapted to be used in the ordinary manner,said Writing-pen B being provided upon the under side thereof in rear ofits point with a perforated guide-lug 0, adapted for the purposes to bepresently set forth. The upper end of the penholder A is open and hassecured thereto an offstanding electrically-controlled perforatingattachment comprising the magnet-frame D, dropping to one side or belowthe same and carrying the electro-magnet E. Secured at one end to themagnet frame and arranged to play over the core of the magnet is theVibrating armature F, to which is secured the auxiliary leafcontactspring G, which is arranged to strike the up- 'vibrating thearmature.

per adjustable contact-screw H. The said contact-screw H is adjustablymounted in one end of the side bracket-arm I, secured to a suitablepoint of attachment andhaving 1ts upper end lying directly over saidcontact spring, so that as the current is passed through the magnetmeans are provided for rapidly WVires 1 and 2 are connected with themagnet-wire and said contact-screw, respectively, to complete theelectric circuit, as will be at once apparent, and may be connected withan ordinary switch X, if desired.

The free end of the armature is provided with a connecting-slot J, whichloosely receives the upper end of thereciprocatlng perforating-needle K.The said perforating-needle passes through the hollow penholder and hasthe point thereof passed through the un der perforated guide-lug C ofthe pen and works under the pen and in a direct line with the pointthereof. It will be readily seen that the perforated guide-lug 0 notonly holds the perforating-needle in a position in a direct line withthe point of the pen,but also serves to hold the pen itself to itsproper position in As the armature is vibrated by the magnet thereciprocating needle is rapidly forced beyond the point of the pen andWithdrawn back of said point, so that as the writing is proceeded withregular indentations or punctures are made directly in the wrlting, andthus cause the ink to run through the paper or into the other materialwhich is being written upon,so that changes, alterations, or erasures ofany character whatever are out of the question.

Removably secured at one end to the under side of the magnet-frame D isthe forked hand-rest L. The said forked hand-rest L provided with theopposite rest-arms M, d1- verging from each other and projecting belowthe under side of the magnet-frame and terminating at their lower endsin the curved feet N, which rest about at the juncture of the wrist andback of the hand, so that the upper heavier end of the pen carrying themagnet is held up from the back of the hand without any effort on thepart of the fingers, and also holds the pen in the proper position forwriting.

The many ad vantages for the improvement herein described are thought tobe apparent without further description.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In an electric perforating-pen, the hollow penholder, the Writing-peninserted in one end of said penholder and provided with a perforatedguide-lug upon its under side, an electro-magnet mounted upon the otherend of said penholder, a vibrating armature controlled by said magnetand provided with a connecting-slot at one end, and an elongatedperforating-needle passing through said hollow penholder, looselyconnected at one end to the slotted end of the armature and adapted tohave the pointed end thereof work through said perforated guide-lug uponthe under side of the pen and in a direct line with the point thereof,substantially as set forth.

The combination, with a Writing-instrument, of an offstandingelectrically-controlled perforatingattachment secured to the upper endof the instrument and a forked handrest removably secured to the underside of said attachment and comprising opposite depending divergentrest-arms terminating at their lower ends in curved feet adapted to restupon the back of the hand, substantially as Set forth.

3. The combination, with a Writing-instrument, of an otlstandingelectrically-controlled perforating, attachment secured to the upper endof the instrument and a forked handrest removably secured to the underside of said attachment, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.

AARON D. LEWVIS.
